1 System
features
The "smart monitoring system" has been designed and developed to give the user a number
of original features which make this system unique. The system is comprised of one smart
monitoring station (STEVAL-IFS014V1) and a maximum of 8 different smart monitoring
nodes (STEVAL-IFS015V1). The smart monitoring station and all the nodes make a
wireless STAR network and all the nodes communicate with the smart station using ZigBee
protocol. The smart station is a handheld device and can be carried by the user from one
place to another. Also the size of the smart monitoring node is small and can be placed
anywhere.
1.1 Wireless
network
The smart monitoring station (STEVAL-IFS014V1) behaves as the coordinator of the
ZigBee network and develops the network with a predefined network ID. The smart
monitoring node (STEVAL-IFS015V1) can connect to the network as the end device. At any
time the complete network can have a maximum of 8 nodes, and the weather parameters of
all the nodes can be seen at the smart station along with those of the smart station.
The user can assign the application node numbers to the nodes which are connected during
the system installation. This gives the user the freedom to assign a specific number to the
connected node and place it anywhere.
Some of the key features of the wireless network are as follows:
●
The system network supports one smart station (STEVAL-IFS014V1) and a maximum
of 8 different nodes (STEVAL-IFS015V1)
●
The user can assign the node number one at a time to the nodes being joined to the
system
●
Whenever a node is switched off or gets out of range, the system detects its absence
and after ~1 minute, this node displays the message "node left"
●
If a node is switched off or gets out of range and comes back, the system detects it and
this node gets its previous user-assigned ID again without any intervention from the
user
●
If, in a working network, the power of the smart station is turned off and is powered up
again, then after complete startup, the system itself recognizes all the previous active
nodes of the system and re-assigns them the user-assigned numbers without any
intervention from the user.
For the smart monitoring system, the following configurations of the ZigBee network have
been used.
